Name that Mathmatics term (Periodic "blank")

I have no idea what the english term for it is. As a result it is more-or-less impossible to find something about it online.

One can give the equation for a sine kurve simply by looking at the graph, taking values such as the amplitute, period etc. and combining them to one equation.

If it is what I think it is, wikipedia seems to have a very limited number of information about it. Any resources on that subject at all would be highly appreciated.

Thank you for your time. Have a nice day.

Periodic function?

ok, we'll try to help find what 'it' is.

I'm not sure one can do that at all.

If you say what the 'it' refers to we might be able to help.
 
I think the term is 'periodic sequence'. Reading the amplitude gives A, the k is (2 * pi) / (period) and b is the phase shift (also directly translated).

y = A sin(kx+b)

?
 
i didn't think there was a term for that. i know I've seen a trig series written using only sines by using certain identities to get rid of the cosine but I've never come across a name for it.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
